In this project, we will learn about IoT Based Soil Nutrient Monitoring & Analysis systems using Arduino & ESP32. Soil is the base of agriculture. Soil provides nutrients that increase the growth of a crop. Some chemical and physical properties of soil, such as its moisture, temperature, soil nitrogen, phosphorous & potassium content heavily affect the yield of a crop. These properties can be sensed by the open-source hardware, and they can be used in the field.

In this project, a soil Nutrient monitoring & analysis system is proposed in which the farmer will be able to monitor soil moisture, soil temperature, and soil nutrient content like Nitrogen, Phosphorous & Potassium. The farmer can monitor all these parameters wirelessly on a mobile phone or the PC System.

To measure the Soil Moisture, we will use a Capacitive Soil Moisture Sensor. The temperature of the soil can be measured using the DS18B20 Waterproof Temperature Sensor. Similarly, in order to measure the Soil NPK Values, we will use a Soil NPK Sensor. All these sensors can be easily interfaced with Arduino.

We will use the Thingspeak Server to Monitor the data in graphical & numerical format. We need the GSM or WiFi network in the field to send the data to the server. But the agricultural field doesn’t have access to these networks. In order to solve this, we will use the NRF2401 Wireless transceiver Module to send the data from sensor Node to Gateway. The data from the transmitter can be transmitted wirelessly from a kilometer distance to the Receiver. The receiver is built using ESP32 WiFi Module, which has access to WiFi Network. Using this WiFi Network, the data can be uploaded to Thingspeak Server.

So, let’s build an IoT Based Soil Nutrient Content Analysis, Monitoring & Testing System simply using Wireless Sensors Network, Arduino & ESP32.
